Pioneer A 109

Pioneer A 109 ... sound better than ever. Pioneer amplifiers are what the dreams of audio lovers are made from - innovative high performance components with extra features and additional connections to all types of speakers and home entertainment systems. Amplification without distortion and stable sound localization leads to what you want: pure sound.

The A-109 is a 40-Watt integrated amplifier that adds a stabilizer for the transformer and chassis. And its symmetrical design results in excellent stereo imagery. The A-109 is among those Pioneer amps to feature the Direct Energy MOS FET transistor directly linked to the speaker output. Efficient input signal transmission with minimum distortion requires the signal path to be as short as possible. The highly efficient Direct Energy MOS FET allowed Pioneer to develop its Advanced Direct Connection, with a shorter signal path and ground line and Symmetrical Construction. This combination ensures that left and right channels are clearly separated and have the same impedance, giving ideal stereo reproduction with identical sound quality. These two design concepts ensure more stable stereo sound localization and a rich sound field.
